Section II Mechanism

2.1 Construction

•The staple sorter consists of the following four functional blocks, paper
transport section, bin driving section, tamper driving section and stapler driving
section.

2.2 Paper transport

The paper transport roller in the staple sorter is driven by the paper transport
motor (M2) (+24V).
(1) When the "Print" key is pressed, the copier begins feeding paper.
(2) When the paper is detected by the paper exit sensor on the copier,the paper
transport motor starts to rotate and transmits drive to the paper exit roller.
(3) The transport motor controls transport speed via pulse. Transport speed is
adjusted as follows:
(a) Paper feed speed
Speed of the paper passing between the paper exit sensor in the copier
and the paper exit sensor (PS1). (Constant speed in all paper sizes)
(b) Paper exit speed
Speed of the paper passing between the paper exit sensor and the sorter
bin. (Paper exit speed depends on paper sizes. Paper exit speed of the
first paper and the following papers may also be different.)
(4) "Paper jam" in the sorter is detected by the paper transport sensors. Jams are
detected when the sensors are not turned ON/OFF within a predetermined
time.
